Lithophane LED Lantern

This is a lithophane LED lantern I built from a camping lantern that I bought from ALDI. I noticed Amazon sells some that looks very similar.

First thing is to take it apart. Remove the inside netting and the spring. On the bottom part ridge there are 3 protrusions of plastic. Use a scalpel or file and carefully remove these.

Now I use the online program at

to make the lithophane. I am including the picture template that you can use. Simply clear the image and use the canvas in your favorite image editing program to add your own pictures within the outline of the template. The template is 36.6 (W)x7.87(H) inches or 90.42(W)x20(H) cm.

Load your image into the program and use the following settings.
Model: Maximum size 247
Thickness 2
Border 0 (Default)
Thinnest layer 0.8 (Default)
